Upper Pulley

There is a night and day difference in performance and really magnifies the intake mods l have. l was joking about a lot but not about first gear. l have big 19″ tires that will now go up in smoke unless l baby the throttle. It was the best mod l’ve ever done. No belt slipping either and my belt is far from new. My old Jag (2001 SVDP) now screams!

Lower Pulley

Just wanted to say thanks for the great job yesterday, the car does feel amazingly more responsive and powerful through the lower and mid range especially.

 

A few more happy customers:

Just a quick e-mail to thank you for your help and quick turnaround on my RR 4.2 supercharger recon + 6% pulley upgrade. VERY, VERY pleased with the result. Thanks again.

Your service was fantastic and we will be leaving feedback accordingly, everybody is always quick to complain but not always so quick to praise when the service is top notch

It made an amazing difference the 10%, so much more responsive and quicker.

Just like to say thank you for excellent service on the rebuild of my Eaton charger.  Could not recommend Powerhouse highly enough, extremely informative and helpful

I would like to thank you for your help and advice on the purchase of these springs for my Jaguar XJ6 X300 3.2 Sport 1997. I have just fitted them 4/08/2013 along with Koni adjustable shocks and powerflex bushes and the car handles very well , but most importantly the ride is still of Jaguar quality 🙂 Even though they are lowered springs my car actually sits very slightly higher than it did before ( however it is 16 and has 163k on her ) and as I suspected was sagging badly… I how have a Jaguar that handles again and looks great. I am very impressed the the quality of this product and your helpful friendly service and will be more than happy to recommend you to others ( I think I said you came highly recommended through the trade anyway ).
